Forum Post: The question of DEI LINK

My env:  dm8168  dvr rdk 4.0

    I want to dynamically change the encode resolution, so I use DEI link before ENC LINK. However ,the quality of image so bad. for example ,

    there are two chains : (1) cap-dis    (2) cap-dei-dis

    it so easy to find: The quality of image after CAP link is better than the one after DEI link.

    I had referenced: http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/287232.aspx

   SO ,Change the Param:

         deiPrm[i_index].enableDeiForceBypass = TRUE

    that the video quality after DEI is good as the one after CAP. But I  cannot dynamically change the DEI output resolution.

    so, how can i fix that problem? thanks.
